AoYa - T19 Protocol

This page provides a public, non sensitive overview of the communication context for the AoYa T19 when used with the Plaspy platform. It explains the role of the tracker reporting protocol and how the device can send location and status information to Plaspy for real time visibility without exposing private implementation details.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol once the device is correctly pointed at the Plaspy endpoint. Exact protocol behavior for the T19 can vary by firmware version, hardware revision, and manufacturer implementation, so this page focuses on practical, high level guidance rather than firmware specific internals.

Protocol Overview​

The T19 reporting protocol governs how the device identifies itself and transmits usable location and event data to a server. At a high level the protocol ensures that Plaspy can receive periodic position updates, motion or status events, and basic telemetry needed for tracking and alerting.

  • Enables the T19 to report location and status updates that Plaspy can display and analyze
  • Provides identifiers and timing information so Plaspy can associate reports with a specific device
  • Carries operational data used for geofence alerts, movement detection, and battery monitoring
  • Allows the device to receive or acknowledge simple server triggered commands when applicable
  • Supports both periodic reporting and event driven messages such as motion or tamper alerts

How Plaspy Detects the Protocol​

Plaspy accepts incoming connections on a single shared endpoint and port and automatically detects the tracker protocol for supported devices. When a T19 is configured to report to the Plaspy endpoint, manual protocol selection inside Plaspy is typically unnecessary.

  • Plaspy listens on the shared server endpoint and determines protocol compatibility automatically
  • Devices that properly target the Plaspy endpoint are usually recognized without extra configuration
  • Detection focuses on matching incoming device traffic to known, supported device behaviors
  • Users typically need only ensure the device reports to the correct Plaspy host and port
  • If automatic detection does not occur, checking device reporting settings and firmware revision is the first step

Transport and Connection Context​

Connection context describes how the T19 can be pointed to Plaspy and which transport options are commonly used. The T19 may be configured to use either UDP or TCP on port 8888 depending on device support and configuration choices. Plaspy accepts both transport types on the same port and provides a stable endpoint for device reporting.

  • Plaspy server domain is d.plaspy.com and the server IP is 54.85.159.138
  • Plaspy uses port 8888 for device connections and all devices in Plaspy use the same port
  • The T19 can be configured to use UDP or TCP on port 8888 based on available firmware settings
  • Using the domain name d.plaspy.com allows the device to follow DNS changes if needed
  • Pointing a device directly to the IP 54.85.159.138 is an alternative for environments where DNS is restricted

Protocol Compatibility Notes​

  • Firmware versions can change how the T19 formats or schedules reports so verify firmware specific behavior
  • Hardware revisions or SKU differences may introduce minor protocol differences between units
  • Manufacturer configuration interfaces may use different default transport settings such as UDP or TCP
  • Ensure the device reporting host is set to d.plaspy.com or 54.85.159.138 and the port is 8888 for Plaspy compatibility
  • Network conditions such as NAT and operator filtering can affect device reachability to the Plaspy endpoint
  • Always cross check compatibility with manufacturer documentation when planning deployments

Why Protocol Understanding Matters​

Understanding the T19 communication protocol helps ensure reliable setup, smoother troubleshooting, and predictable long term behavior when devices report into Plaspy. A clear view of how the device connects and what it reports reduces time spent diagnosing connectivity or data issues.

  • Speeds up initial setup by confirming transport and endpoint settings are correct
  • Helps pinpoint whether an issue is network related, configuration related, or firmware related
  • Informs decisions about transport selection for reliability or battery life trade offs
  • Supports better planning for fleet scale deployments and monitoring expectations
  • Reduces false alerts by aligning device event reporting with Plaspy configuration

Why Use Plaspy with This Protocol​

Using the AoYa T19 with Plaspy gives organizations compact, long life tracking combined with a platform that automatically accepts device reports and identifies the appropriate protocol. This combination is well suited for asset tracking scenarios where discreet mounting, extended battery life, and reliable server ingestion are important.
